Eaton 12Z-612-BG Hydraulic Hose Female Swivel Fitting

Product Description

The EATON 12Z-612-BG is a straight female swivel fitting designed for hydraulic hose assemblies. It connects hydraulic hoses to ports and adapters using a 1-1/16-12 threaded SAE interface, conforming to SAE J1176 standards. The fitting features a 0.75 inch hose inside diameter and 0.75 inch outside diameter, sized for 3/4 inch (dash-12) hose. Constructed from steel with a 1-inch hex, this fitting is suitable for demanding hydraulic system environments where secure, leak-resistant connections are required. Licensed hydraulic technicians and fluid power specialists are the primary installers for this component.

This fitting is part of the EATON Z Series and is intended for use in hydraulic systems requiring an SAE-compliant female swivel connection at the hose end. The straight configuration makes it appropriate for applications where a direct in-line connection is needed without angular offset. Typical installations include mobile hydraulic equipment, industrial machinery, and fluid power circuits where 3/4 inch hose assemblies are routed to fixed-thread ports.

Key Features

• Female swivel design allows the fitting to rotate during assembly, reducing hose twist and torsional stress
• 1-1/16-12 thread size meets SAE J1176 standards for reliable sealing
• 0.75 inch hose inside diameter fits standard 3/4 inch (dash-12) hydraulic hose
• Straight shape provides direct in-line routing without angular offset
• Steel construction for durability in high-pressure hydraulic environments
• 1-inch hex size for standard wrench installation and torque application

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and fully bleed the hydraulic system before removing or installing any fittings. Use a proper open-end or combination wrench on the 1-inch hex to tighten the fitting; do not use the hose body as a torque reaction point. Verify thread compatibility and SAE conformance before installation to ensure a leak-free connection.
